- Referring now to the drawing, 1 represents the base or setting-of the producer,

said base being hollowed out as at 2toprovide a receptacle for the ashes and for the water which. seals the lower end of the ap-.. Y

ment illustrated in Fig.- 1 are shownas radiating from the center, said boxes receiving the blast from a blast. pipe 4 which exthrough-the baseof the boxes. In the embodiment shown in Fig. 2 the twyer boxes are .shown as extending inwardly from the fixed lower section: 5 of the producer, toward the center but terminating short thereof. These twyer boxes are adapted to receive the blast through plpes 6 from a bustle pipe 7 which encircles the lower portion of the producer. The

bustle pipe in turn receives its blast from it will be-n'oted are supported beneath the water seal in order to prevent their supports'9 from becoming overheated, thus prolonging the life of said supports. The ashes deposited in receptacle may be removed in any desired manner but, I'preferably employ Archimedes screws 10, three of such screws being shown in the present instance, said screws delivering the ashes upon the traveling belt or carrier 11 encircling the lower portion of the producer and driven as by means of a pulley 12 which may be driven from any suitable source of power supply.

The producer which, in the present instance, is of cylindrical form is provided with a fixed upper section 13 between which and the lower fixed section ,5 is provided a revoluble section 14, adapted to be rotated as by means of a gear wheel 15 upon the shaft 'paratus. The twyer boxes 3 in the embodi- 16 which meshes. with peripheral teeth 17 located upon a revoluble section 14. Shaft 16 may be rotated from any suitable source of power supply, the means provided in the present instance being a. shaft 18 having a beveled gear 19 meshing with a similar-gear upon shaft 16. The upper fixed section 13 of the producer may be supported in any desired manner, for instance as by means of the supports 20. .Seals as at 21 and 22 are provided between the revoluble section 14 and the fixed sections 5 and 13.

The top portion or cover 25 of the producer is mounted to revolve upon the top section 13, being supported in the present instance as by means of ball bearings 26. A water or other seal 27 is provided between the upper section and said cover for preventing the escape of gas. Cover 25 may be revolved by any suitable means as by the gear 28 upon the shaft 16 which meshes with peripheral teeth 29 provided upon the edge ofthe cover. The cover is provided with an aperture 30 through which extends a rotatable poker 31 the lower end of which is offset as shown, said poker being provided with a suitable apron 32, which dips into a water seal 33jlocated upon the cover. The cover is also provided with an aperture 34 through which extends a chute 35 said chute extending downwardly from its lower end into the producer from a hopper 35 Extending downwardly through the hopper is a shaft 36 provided with a plurality of laterally projecting members 37 which are received between similar members extending inwardly from the inner walls of the hopper. Shaft 36 near its lower end is rigidly connected with the apertured plate 37 which rests upon asimilar plate 38 extending transversely of the hopper between the same and the chute. These two plates form a valve, so that when the apertures are in registry, fuel in the hopper falls into the producer and when said apertures are outof registry a closure will be eifected between the interior producer and the hopper. Below the plate 37 the shaft 36 is connected with the chute 35, so that as the shaft 36 is rotated the chute turns with it. A cover 39 is provided for hopper 35 Shaft 36 extends through cover 39 and the upper end of said shaft is provided with a pinion 40 which meshes with the gear teeth 52 carried upon .the gas exit conduit 41 extending upwardly from the producer. v

Formed interiorly of the producer and supported upon the inner walls of the revoluble section 14 is a partition 42 said partition being arched as shown, and having semi-circular apertures 43 extending therethrough, which apertures form passage ways for the fuel and the gases. Four of these apertures are provided in the present instance, said apertures being formed between legs 44 which rest against the inner wall of the revoluble section 14. Leading upward from the aperture 45 formed in the central portion of the arch or partition 42 is a gas delivery conduit 46, the upper end of which terminates ad]acent cover 25,,

and it will be observed that since partition 42 and conduit 46 are carried by section 14 they revolve with it. The conduit 41 which extends upward from the producer forms a continuation of the delivery conduit 46 It will be evident that when the cover 25 is rotated, and the poker rotated, the shaft 36, through gear wheel 40 and gear 52, will also be caused to rotate, so that the fuel is simultaneously distributed and agitated. A water circulation is maintained in poker 31 by means of an open ended pipe 55 extending downwardly into the poker, said pipe receiving its water supply by means of the hollow shaft 50 from a pipe which, in turn receives its supply from a trough 56 extending about conduit 41, said trough being suitably carried upon the cover portion 25. Water may be delivered to this trough as by means of a pipe 57. The water which is deli 'ered into the poker flows upwardly and is discharged on top of the producer as by means of the pipe 58 connected with the upper end of the poker.

A blast pipe 59 leads into the upper portion of the producer and is provided with a suitable damper 60. This blast pipe leads from the conduit 61 which is positioned about the stationary gas conduit 41, conduit 61 leading from a source of air or carbonicacid gas supply. The object of positioning conduit about the gas discharge conduit is to heat the incoming air or other gas which is to be discharged into the produce-r. In Fig. 2 of the drawings I have shown spirally arranged baffles 62 within the conduit and interposed between the inner-walls thereof and the exterior wall of the conduit. This construction insures that a greater'volunie of the incoming air or other gas shall be brought into intimate contact with the gas discharge conduit, whereby a greater portion of the heat is extracted from the outgoing producer gas. Blast pipe 4 is provided with an upper extension or purge pipe 63 provided with a removable cover portion 64.

66and 67 denote inspirators which lead into pipes 63 and 71, said inspirators beingadapted to receive steam from pipes 68 and 69 connected with the pipe 70, the latter leading from any suitable source of steam supply.

The, connecting portion 71 of blast pipe 4 gas discharge which extends between inspirators 66 and 67, is suitably valved as at 7 2. Each of the inspirators may be provided with valves such. 'asare indicated diagrammatically in Fig. 9, the purpose the quantity of air admitted to the desired nicety.

Having thus described the construction of this embodiment of my invention the operation thereof which to a large extent should be obvious, is substantially as follows: The fuel which in the present instance is bituminous coal may be introduced into hopper 35 by suitable means as, for instance, a funnel 73 which may be independently supported above the producer, in such position that when the hopper 35 is underneath the same, fuel may be discharged into said hopper, and when a suitable quantity thereof has been introduced into the hopper said fuel may be ignited in the usual manner. When the apparatus is in operation the intermediate portion of the apparatus and the cover are rotated as above described. Inasmuch as chute 35 and poker 31 are carried upon the cover they will be rotated independently by the gear wheels 54 and 51 which mesh with the gear wheel53 upon the stationary The fuel will therefore be conduit 41. evenly distributed upon the bed thereof in the upper section of the producer, and the poker being offset as shown will maintain the bed free of fissures or crevices which might otherwise be formed therein. The various dampers in the blast pipe may be regulated to admit the proper amount of air or gas both into the upper and lower parts of the producer. The gas formed in the upper portion of the producer passes downward through the aperture of the arch and mixes with that passing upward through the bed. The gases thereupon pass upward through conduit- 46 which leads from the central portion of arch 42 and it will be observed that this conduit forms a mixing chamber located entirely within the producer. It will accordingly be seen I have provided a construction well adapted, among others, to attain the several ends and objects of the invention in a simple yet eflicient manner.

It will be obvious that by reason of the connection shown between the blast pipes and the producer, gases of various qualities and compositions may be produced; For instance a sufficient quantity of steam may be discharged into the bottom of the producer to produce water gas which gas, will mix with the rich hydrocarbon gases passing downward'through the arch to form a gas of high calorific power.

As many changes could be made in the above construction and 'many apparently widely difierent embodiments of this invention could be made without departing froin of which is to regulate the scope thereof, itis intended that all matshown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein de-' scribed and all statements of the scope of the invention, which as a matter of language might be said to fall therebetween;
